Winner Miguel Romo and his co-workers found out Wednesday night that the group's ticket matched all six numbers from the Oct. 14 drawing, according to a press release from California Lottery.
Romo said in the release that he got a call from Overland Liquor, where the ticket was purchased. The retailer told Romo his shop sold the winning ticket and advised him to check his numbers.
The group works for a company that does apartment maintenance, and they've been pooling their money twice a week for around three years in hopes of winning the big one.
The group plans to take the lump sum amount of $4.5 million, which ends up being $300,000 before taxes when split 15 ways. The lucky 15 claimed their winnings on Thursday. Romo says he plans to buy a house for his family and invest it wisely for his children.
The owner of Overland Liquor received $35,000 for selling the winning ticket.
